Misunderstanding and resenting Lu Xingchen for scheming against her, she threatened to divorce him and even terminated their pregnancy, which caused her heart condition to relapse. Desperate and heartbroken, Lu Xingchen could not bear to watch his beloved die, so he sacrificed his own heart to save her. Sang Wan, having been saved, was kept in the dark and believed he was being unreasonable, so she ran away from home.

Eventually, she realized she loved him and frantically set out to find him. Yet, as the truth gradually unfolded layer by layer, through her memories and her love, she received the devastating news of his death—and rushed to the crematorium to be with him.
